I guess there must be a handful of extremely rich and utterly unscrupulous people who would be willing to pay a huge amount for a well-known piece of art and hang it in a place where only they could enjoy it. It probably gives some people an immense feeling of power to think that they are denying the rest of us something which, by rights, should belong to everyone.

Hopefully, it was just stolen by a couple of hoodlums who aren't smart enough to realize the difficulty of fencing so famous a piece and it'll either turn up in a few months or their attempts to sell it will get them busted.
